John F. Kennedy High School senior Regine Tugade added a new accomplishment to her career Friday night, breaking the Guam national record for the 400-meter race — shattering the previous mark by almost three seconds.

With a time of 57.89 seconds at the Independent Interscholastic Athletic Association of Guam track meet, Tugade broke the previous record of 60.12 seconds, set by Naomi Blaz in 2011.

To put things in perspective that would be like breaking a 100-meter record by a half second. At the pace she was running, had Tugade been running against Blaz when she set her record, she would have beaten her by 15.5 meters.

“Naomi actually used to be my teammate for both JFK and the national team,” said Tugade. “But at the time, I was never a 400-meter runner. Breaking the 400-meter record felt like an even bigger accomplishment than any of my other records. I was more relieved after finding out my time because it was my first and last chance to be able to capture the record.”

What makes this even more exceptional is that Tugade usually doesn’t even run the 400-meter event. Friday’s race was the first time she ran it this season.

Last season she only ran it once, close to the record with a time of 60.78 seconds. She surprised herself with her time last year, and did it again this year by not only breaking the record, but shattering it.

The All-Island Track Meet will begin May 12 with discus, shotput and high jump, with the rest of the events taking place on May 13.
